Callichirus Kraussi
''Kraussillichirus kraussi'' (Stebbing, 1900), commonly named the common sandprawn or pink prawn, is a species of ghost shrimp, an African crustacean in the family Callichiridae. Distribution and habitat This species occurs along the coast and estuaries from Lambert's Bay in the Western Cape, around the Cape and northwards along the Indian Ocean coastline to Delagoa Bay in Mozambique. It is well-adapted to life both in the littoral zone of sheltered marine bays and of estuaries. Taxonomy The common sandprawn was first described in the literature by the Rev. Thomas R. R. Stebbing, an ardent Darwinist who had been banned from preaching; the type specimen was collected at " Gordon's Bay, a little below high water mark", and placed in the genus '' Callianassa'' established by William Elford Leach in 1814. The species was subsequently moved to the genus ''Callichirus'' and, most recently, to the genus ''Kraussillichirus''. Description The original description reads: Ec ...

Edward Percy Stebbing
Edward Percy Stebbing FRSE FRGS FZS (4 January 1872 – 21 March 1960) was a pioneering English forester and forest entomologist in India. He was among the first to warn of desertification and desiccation and wrote on "The encroaching Sahara". In 1935, he wrote of the "desert whose power is incalculable and whose silent and almost invisible approach must be difficult to estimate." He suggested that this was man-made and this led to a joint Anglo-French forestry mission from December 1936 to February 1937 that toured northern Nigeria and Niger to assess the danger of desertification. Life He was born in London on 4 January 1872, and was the second son of Edward Charles Stebbing (b. 1839). He was educated at St Paul's School, London. He then studied at the Royal Engineering College and Coopers Hill College (which specialised in training for the Indian Forest Service). He then studied at the University of Edinburgh and graduated with a MA. From 1900 to 1910, he worked as Fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endopod
The arthropod leg is a form of jointed appendage of arthropods, usually used for walking. Many of the terms used for arthropod leg segments (called podomeres) are of Latin origin, and may be confused with terms for bones: ''coxa'' (meaning hip, plural ''coxae''), ''trochanter'', ''femur'' (plural ''femora''), ''tibia'' (plural ''tibiae''), ''tarsus'' (plural ''tarsi''), ''ischium'' (plural ''ischia''), ''metatarsus'', ''carpus'', ''dactylus'' (meaning finger), ''patella'' (plural ''patellae''). Homologies of leg segments between groups are difficult to prove and are the source of much argument. Some authors posit up to eleven segments per leg for the most recent common ancestor of extant arthropods but modern arthropods have eight or fewer. It has been argued that the ancestral leg need not have been so complex, and that other events, such as successive loss of function of a ''Hox''-gene, could result in parallel gains of leg segments. In arthropods, each of the leg segments artic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Axiidea
Axiidea is an infraorder of decapod crustaceans. They are colloquially known as mud shrimp, ghost shrimp, or burrowing shrimp; however, these decapods are only distantly related to true shrimp. Axiidea and Gebiidea are divergent infraoders of the former infraorder Thalassinidea. These infraorders have converged ecologically and morphologically as burrowing forms.Dworschak, Peter C. (2012). ''Treatise on Zoology - Anatomy, Taxonomy, Biology. The Crustacea, Volume 9 Part B''. BRILL. pp. 109–100. . Based on molecular evidence as of 2009, it is now widely believed that these two infraorders represent two distinct lineages separate from one another. Since this is a recent change, much of the literature and research surrounding these infraorders still refers to the Axiidea and Gebiidea in combination as "thalassinidean" for the sake of clarity and reference. This division based on molecular evidence is consistent with the groupings proposed by Robert Gurney in 1938 based on larva ...

Diversity And Distributions
''Diversity and Distributions'' is a bimonthly peer-reviewed scientific journal on conservation biogeography. It was established in 1993 as ''Biodiversity Letters''. The journal covers the applications of biogeographical principles, theories, and analyses to problems concerning the conservation of biodiversity. The editors-in-chief are K.C. Burns, Luca Santini, and Aibin Zhan, who took over from Janet Franklin in 2019. After over two decades as editor-in-chief, David M. Richardson stepped down from the role in December 2015. According to the ''Journal Citation Reports'', the journal has a 2018 impact factor The impact factor (IF) or journal impact factor (JIF) of an academic journal is a scientometric index calculated by Clarivate that reflects the yearly mean number of citations of articles published in the last two years in a given journal, as i ... of 4.092, ranking it 2nd out of 37 journals in the category "Biodiversity Conservation" and 20th out of 134 journals in the categ ...

Marine Biology
Marine biology is the scientific study of the biology of marine life, organisms in the sea. Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy. A large proportion of all life on Earth lives in the ocean. The exact size of this ''large proportion'' is unknown, since many ocean species are still to be discovered. The ocean is a complex three-dimensional world covering approximately 71% of the Earth's surface. The habitats studied in marine biology include everything from the tiny layers of surface water in which organisms and abiotic items may be trapped in surface tension between the ocean and atmosphere, to the depths of the oceanic trenches, sometimes 10,000 meters or more beneath the surface of the ocean. Specific habitats include estuaries, coral reefs, kelp forests, seagrass meadows, the surrounds of seamounts and therm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Swartvlei
Sedgefield is a coastal town on the Garden Route in the Western Cape province of South Africa. It is situated on the N2 national road, between George and Knysna. The town was proclaimed in 1929 on the farm Sedgefield, which in turn was named in 1894 after the village of the same name in the UK where the father (Henry Barrington) of the then farm owner was born. History The farm Ruigtevlei was granted to the widow Meeding by Lord Charles Somerset and upon her death in 1878, the farm was divided into 9 lots. Lots A and B were first bought by individual farmers, before eventually being purchased in 1894 by John Barrington, son of then-famous politician, farmer and industrialist Henry Barrington (referred to as ‘Henry Barrington of Portland’ in the novel ‘Circles in a forest’ by Dalene Matthee). John named the town in honour of his father's birthplace Sedgefield in the United Kingdom. Kate Maurice (née Barrington) inherited the farm Sedgefield from her brother upon his deat ...
